hello

basically i have a piece of cat5 stuck up the ass of a faceplate into my bedroom, the other side is downstairs (no faceplate) sitting around near the cable modem:

rj45--------WALL|FACEPLATE

LOL I'M GONNA BUY THIS

Can i use two of these (one stuck in my room, the other on the "loose" end of the cable (joined by a cat5 inline joiner deally)) to use both a phone and computer in my room?

thx!

so lemme get this straight you want to use the same cable for a phone line and a network cable, and you want to be able to switch between the two or use them at the same time?

You can use a single piece of Cat5 cable for voice and data. Punch down the white and blue for voice and the white and brown and white and green for the data. I think that's the right splitter - there are a few, E2 U2 I think. I'd get a sparky to do it for you :)

would a sparky do telephone lines? wouldn't someone from his service provider (telstra/optus/whatever) be more suitable? As for cat5 cables, they're a piece of piss to make yourself so why would you bother? Unless there's some stupid law that says permanent cat5's must be done by a professional.

^^ Yes they would do telephone lines. That or a certified cabler.

What's making cat5 cables got to do with installing V + D ?

because he's not installing anything, he's just connecting some plug s*** up, I think I kind of misinterpreted the loose part as dangly wire with no plug but looks like it has a plug and he's just going to plug a double adapter on each end.

thanks for the replies

the dangly part does have a connector on it.

my pc is upstairs, but the router is downstairs, so i have (already) a cable coming from the router, up through the floor and attached to a faceplate. so i've got a 'female' end in my room that i want to put that double adaptor on and shove my phone and computer into.

downstairs i want to have another double adaptor connected to that dangly bit of the wire that's connected currently to the router. from the double adaptor it'll go to both the router and the rj12 telephone line. i'll solve the male -> male problem by using one of those inline convertor thingies

when i read the replies i kinda lolled and realised i could just split the cables, but it's not really practical as the phoneline is a few meters from the router and i'd have meters of unshielded cat5 roaming around, and a similar problem upstairs

i guess i'm asking if anyone's had any experience with these double adaptors and if there's any problems with my plan before i go make a fool of myself at jaycar

just buy one of those internet phones that plugs into your router it would be easier


alternatively you need an rj12 crimper like the one in my truck, then you can use one of the redudndent pairs in the cat 5 cable to run the phone line down

Wouldn't it cause lag or some s*** if the phone was being used at the same time as the computer since more data is being pushed through the one cable? I dunno though just my 2 cents.

no it would not lag becase the psdn(normal phone) line would be on different pairs to tx and rx

Ah ok then. Well I stand corrected. Learn something new everyday.

Actually I've heard that using the same piece of UTP cable to run voice and data can sometimes lead to interference with either service...

f*** up hunter. your input is not appreciated in this thread.

don't get technical ok? OK? OK?

Yes you can. It's how we've got the office wired here. Basically we can plugged our PABX phones into the data port/vice versa, all we have to do is switch where the port goes to at the patch panel i.e. if it's voice it goes to the PABX, if data it goes to the data switch.

Ethernet uses 4 wires, normal voice lines use 2 wires... Cat5 has 8 wires

Austel may not approve but it definately works.

Unless you are running gigabit ethernet where it uses 8 wires.

100mbit uses wire 1 2 3 and 6. which leaves you pairs 4 5 and 7 8 for voice.

just do some co-ordinated crimping and ur set.
